Application filed November 27, 1895. Serial No. 570,315. (No specimens.)

To all whom it may concern:

lle it known that l, LEOPOLD S. SAMUEL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Soap Cakes; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it zipperin-ins to make and use the some, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form part of this specification.

This invention relates to that class of soap cakes referred to more particularly in my prior patent, No. 549,687, in which each cake comprises two or more sections of different \utrietics oi soup OiSiLPOllfLCGOllS mutter united permanently by we or ccinentitious matter.

The particular object of this invention is to secure a. more rigid" union of the sections.

The invention cousistsin theiuiprovcd soup m ige and in the arrangements and combineiions of parts, all substantially as will be hereiuu-i'ter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding paris in each of the figures, Figure lis a section of the soap cake in one of itsforms. Fig. 2 is an inside view of one of the sections thereof, audhig. 3 is u dotuilshowing a roughcued surface whichnmy be employed.

in said drawings, (.L is the female and b the nmleiuensber of the soap cake, and c is u ceincniiiious or combining substance adapted to u ite the said sections whcu employed with certain co -operating constructions horciuul icr reifin-rod to. The said uniting substance is preferably of wax. 'lho vuriciy oi. wax, prci'crrwl is ccrosiuo.

lu ihc prolfcrrcd construction l form. in tho i'cmulc section. a shu'llow depression, usshown in Fig. .l, the side walls of which are under-- but or rcrcrscly dovetailed, as at c. The male section is provided with u dovetailed projection r l',coni 'oriuiug more or less closely to the recess or depression in plan. ziud extending into the shallow recess, ihc lzucrul edges being wrrcspinulingly uiulcrcut. Into the shallow depression, in the operation of uniting the I sections, l pour liquid wax or cerosine and then press the projection of the male member into the said recess. By this operation the wax is forced outward to some extent and into the joint formed between the sections, fOlIili n g, when solid, what may be termed akey or feat-her between the undercut surfaces,

which acts to firmly unite the parts.

By means of the undercut surfaces and key or feather referred to the soap sections are held together firmly even though the key may have little or no adhesive affinity for the soap.

1 may, in addition to the large recess and projection, shown, roughen the surface of the. soap cake. or form small indentations, scratches, and the like, so that when the liquid or fluid cerosine is forced out of the recess it will. enter the recesses and interstices of the roughened surfaces, and thus more thoroughly and perfectly unite the parts.

Having thus described the invention, what I claim as new is- 1. The improved soup cake herein described, in which are combined suponaceous sections a, Z), having undercut surfaces and {a solidifiable fluid hardened within the recesses formed by said undercut surfaces and locking said sections together, substantially as set forth.

2. 'lhe improved soap cake herein described, in which are combined a plurality of different saponziceous sections a, Z), having male and female ports held together by a key substance, the contiguous surfaces of said sections 0;, I), being; roughened by indentations, scratches, or the like, whereby the key substance will more perfectly unite the parts, substantially as set forth.

3. The iuipro ved soup cake herein described, in which are combined a plurality of different saponuoeous sections a, b, having undercut iuulcuiul l'ciuulo pin-ls projecting one into the other, and u solidified key substance, substantially as set forth.

4-. 'l he improved soup cake herein described, in .Wll ich are combined uplurulity of different snpounoeous sections a, I), having undercut ports, undn non-hygroscopic substance adapted to be pressed into conformity to the surface of the sections and s rve us akey for holding said parts together, substantially as set forth.

i 5. The improved soap cake herein describ ed in which are combined a plurality of same- 5 naoeous sections a, I), having undercut sur faces of a binding-wax underlying said 1111 derout surfaces, substantially as set forth.

In testilnony thatI claim the foregoing I have hereunto set my hand this 25th day of November, 1895.
